Hey guys, 73' 240z with an L28 dual webers, recent replacement of distributor, cables, battery with car running fine. After having a massive fuel leak from the tank I took my spare to get treated and sealed with all new sending unit and fuel lines in the rear with deleted vapor tank. Z is currently running on mechanical pump (still new).
With the tank install and deleted vapor tank my idle is weak. Now I'm talking flutter at -500 with a nasty shake and not very responsive to throttle past 2800 rpms. Any suggestions?
